Long Division (Two-Digit Dividend)

This video tutorial teaches how to divide a two-digit dividend by a two-digit divisor using long division. It explains the DMSB process: Divide, Multiply, Subtract, and Bring down. The tutorial demonstrates the steps with the example of dividing 51 by 17, including estimation techniques for easier calculation. The lesson concludes with the final quotient and a recap of the division process.

What is the first step in setting up a long division problem?

• Draw the long division symbol and place the dividend inside.

• Write the divisor inside the division symbol.

• Subtract the divisor from the dividend.

• Multiply the dividend by the divisor.

In the first round of DMSB, why is a zero placed in the quotient?

• Because 5 is a multiple of 17.

• Because 17 does not fit into 5.

• Because 5 is larger than 17.

• Because 17 goes into 5 exactly once.

What is the purpose of rounding the divisor to 20 in the second round of DMSB?

• To make the division more complex.

• To avoid using multiplication.

• To ensure the divisor is larger than the dividend.

• To simplify the estimation process.

How many times does 17 fit into 51 according to the estimation?

• Five times

• Two times

• Three times

• Four times

What is the final quotient when dividing 51 by 17?

• 2

• 4

• 5

• 3
